CP2103-GMR Description

Short technical summary and product information.

The Silicon Labs CP2103-GMR is a highly integrated single-chip USB to UART bridge controller. It simplifies the design of USB-to-serial communication by eliminating the need for external resistors and crystals. The device supports USB 2.0 full-speed (12 Mbps) and provides a UART interface with data formats including 5, 6, 7, and 8 data bits, 1, 1.5, or 2 stop bits, and various parity options. It supports baud rates from 300 bps up to 1 Mbps.

 

Key features include an integrated 1024-byte EEPROM for configuration, on-chip power-on reset, and a 3.3V voltage regulator. The CP2103-GMR includes four GPIO signals for status and control, and supports RS-485 mode with bus transceiver control. It is designed for applications such as upgrading legacy RS-232 or RS-485 devices to USB, and creating USB interface cables for cellular phones or PDAs.

 

This IC is supplied in a lead-free 28-pin QFN package measuring 5x5 mm. It is designed for surface mount applications and operates within a temperature range of -40°C to +85°C. The device can be self-powered from 3.0 to 3.6 V or USB bus powered from 4.0 to 5.25 V.
